I have three basement windows like the ones in the pictures. They are all 30" wide and 14" high. As you can see, they are all above the ground (80" & 130" respectively). With such small windows, the basement doesn't get good ventilation and natural light. My question is whether it is easy to cut down part of the wall under the windows and replace them with the bigger ones like 30" by 48". Do I need a permit and how much will it cost do each one. My basement is finished.
A permit is going to be required. Before going to far, you should verify the limiting distance and check the area of unprotected openings you're allowed.
We were looking to enlarge a window, we were told going down was far less expensive (something like $650/opening) than going wider ($2500/opening). More structural modifications involved with going wider than going down was the reasoning.

You will want to avoid widening the opening if you are looking at the easiest/cheapest solution
Widening the opening will require at a minimum (permit required as well):
a new steel lintel for the brick
a new wood header/beam (not only for the floor joist, but there is always the potential of needing to support a point load which may not be visible unless you remove drywall)
floor framing may be framed to match the current opening size. Widening the opening will require altering the floor framing as well.
When I had my basement finished, my GC subcontracted the windows portion. It costs anywhere from $800-$1200 to enlarge or open each new window. Since your basement is finished, you will have to protect the interior well as it is a messy job. Call around and get quotes.

Which is incorrect the permit or the unprotected openings limitation?
Sorry, the “permit is going to be required” piece. It’s unlikely a permit will be required, but you are right does depend on the distance between houses and number/square feet of openings.
Well last year, I had 2 egress windows installed in my finished basement. I needed a permit, also the city I live in had a limit on the number of windows you can have on a cement wall. It came to 2500 per window. That's including , making a bigger hole, installing a new header, removing siding and re-installing, the egress window was included in the price.
Check with your city for what they require.
