Fujifilm gf 45mm f 2 8 r wr vs fujifilm gf 50mm f 3 5 r lm wr?

Both are autofocus primes for Fujifilm's medium format (44 x 33) GFX bodies, and neither has stabilisation. They differ mainly in speed and framing.

The GF 45mm f/2.8 R WR is the brighter lens. It frames like 36mm on full frame, and at f/2.8 it gives about the depth of field of f/2.2 there, so it's the better pick for low light and more background blur.

The GF 50mm f/3.5 R LM WR is the smaller lens, and the smallest in the GF range. It frames like 40mm on full frame, a little tighter, and at f/3.5 it gives about the depth of field of f/2.8 there.

If you want to carry something light and shoot in daylight, take the 50mm. If you shoot indoors or want softer backgrounds, the 45mm is the one. For the exposure and depth-of-field maths behind this, see the focal length converter.
