Cousing it to vabrate and stalls

My KIA is engaging gears with difficulty,the reverse gear is making noise and do not want to engage,what should i do.

Problem is km is not working. Rpm, km, petrol & heatmeter all is not work. I change km but not work same same problem. Give me solution.

Both the rear lamps and the brakes lights do not turn off.

I own a manual Kia and I feel that the gears are set with lots of difficulty. I need to press the clutch deeply so that the change is made softer. Is this normal?
