To extract R squared values, you can use
summary(lm1)$r.squared
and include it in the cbind as
result1-cbind(summary(lm1)$coef[,1],summary(lm1)$coef[,1],summary(lm1)$r.squared)
To add the results of multiple outputs you can use rbind such as

No, using paste/as.formula you can do it in a loop. Example:

y1 - x1 + x2 + rnorm(100)
y2 - x1*runif(100, 0.5, 1.0) + x2 + rnorm(100)
