Although you can change the pixel resolution to be higher with an Image Size/Resize function (with Resample selected), the results are likely to be disappointing.
When the software adds pixels, it has to make them up based on the surrounding original pixels. If you do too much of this, the image edges get soft and colors blur.
Your best bet is to take the highest resolution that you can (borrow a higher resolution camera if necessary). Then take the output to a professional printer and see if they can make a satisfactory poster. Sometimes quality pictures will yield satisfactory posters, especially if they will not be hung so they can be examined closely.
Good Luck

Depends on the size of the original. If you use Photoshop or Paintshop you can change the dpi to a higher number. Your image may look pixelated if you go too large.

No. If you're image is smaller than poster size, it is unlikely to already be any higher than 300 res -- once enlarged your res will be degraded. Settle for higher numbers, 300 is good one.

That depends on the resolution and viewing distance.
If it's viewed from 20 feet away, it might be OK.
