Need more info really - what are the numbers written on the side of the present tyres? Tell us those and well go on from there.
The rims will accept pretty much any commonly available "26"" tire (as in 559 ISO), probably happiest with 1.5"-2.2" widths. Frame can accept who knows what widths, as wide as 2.2" is common on dirt intended mountain bikes but a simple measurement will tell all. First photo seems to have a tire mounted which is on the narrower end of the width range, but w/out any tire size info who knows. Second photo shows a tire with a mixed tread, common on lower cost mountain bikes where the rider might do some soft ground riding but also some pavement riding (the tread has center rib or line of connecting blocks to make straight ahead rolling smoother and the side portions of the tread has more open blocks for digging into soft surfaces). The third photo looks to be a more street/prepared trail tread. More like a car's summer tires and less like a mud and snow one.
As said above, more info to what you have used, your impressions of the old tires, your wishes with the new tires will help us advise you. Andy.
I should have also mentioned that a visit to a LBS would answer these and other questions that the OP might have. Andy.
The OP is taking pictures of tires at the local Wal-mart.......
Either tire in the photo will most likely fit the bike. The first has a little bit of off-road ability. The 2nd is strictly a street tire.

As Andy said. The OP can buy any tire marked 26 x 1.XX. If he looks at his old tire he'll see the width on that, then can decide whether to go wider or narrower within a band based on his preference.

Looks like the tires are on the wide side for your rim, but should be ok.

Alright, I cleaned up the off topic posts here.
thank you very much for all your reply. Sorry i did not reply much earlier.
I really just need to replace my bike tires so I can bike to work. Really do not know about wider, narrower, on road, off road
Yes I took these pictures at Walmart store since these are the two types of tire they carrying at the store.
Just have a closer look on the tire. this is the information on the tire. 26x1.90 (5.0- 5.9). I think this is the tire size then.
Does anyone have any suggestion for type of tire ? Again, Thank you very much for the help. Thank you
That information helps a bit. On tire sizes, the first number is your diameter and the second is the width. So, a 26x1.90 will be 26" in diameter with width of 1.9". When choosing new tires, you must stay with the proper diameter (in your case 26") to fit your rim. You have a bit of leeway in the width, but if you go too wide, you will have problems fitting the tire between your brakes and/or frame and fork. If you go to narrow, you will have issues seating it properly on the rim.
Since you're new to this, I'd suggest going with a width very close to what you have now and selecting a tread pattern appropriate for your riding habits. As many above have mentioned, you can probably go from a 1.5" to 2.2" width with your current tires being at 1.9". You will need to choose a width and suitable tread pattern depending on how much road versus off-road riding you do. Generally, the smoother and narrower tires will provide better performance on-road and the knobbier and wider tires will provide better off-road performance. You'll have to make this determination for yourself.
