Sorry, you said you wanted separate lb/ub for your newvars:
****
clear*
set obs 100
gen id=_n
//lower bound for var1
local a1 40
//upper bound for var1
local b1 100
//lower bound for var2
local a2 56
//upper bound for var2
local b2 76
//lower bound for var3
local a3 74
//upper bound for var3
local b3 88
//lower bound for var4
local a4 45
//upper bound for var4
local b4 67
forv i=1/4{
gen var`i'=`a`i''+int((`b`i''-`a`i''+1)*runiform())
}
gen var5cat=0
replace var5cat=1 in 51/100
list, noobs h(30)
****
