Do we have any other evidence other than red shift? Is anyone trying to disapprove inflation? Also, can red shift occur because of large distance, not only because two objects are going farther from each other?

The evidence is in the red shift of the light received from galaxies. Farther the galaxies, more is the red shift. Red shift is caused if source of light is moving away from us.
How far a galaxy is, is figured with the help of supernova (a standard candle). Scientists know how bright the supernova of a certain class should be depending upon how far it is.
The brightness of Supernova gives the distance
Red shift of supernova light and matching red shift of galaxy light tells that galaxy is at same distance as the supernova.
Farther the distance, more red shift confirms that farther galaxies are moving away faster indicating universe is not only expanding, the expansion is accelerating.
There are bunch of documentaries on youtube that explain this.
