Static routes aren't allowed in the lab, so you're better of finding and
practicing other ways.

Why can't we use static routes to aid this kind of redistributions to match
the igrp or RIP mask. Does that method have any short fall.

Yes, but actual job R5 doing as ABR (area range 170.10.128/24) not R4
with its summary etc. This summary doesnt mean anything (of cause if ip
split is enabled in IGRP network). If you look at ip ospf database
you should see 170.10.128 as IA summary but its not external.

Yes, if there's no routing loops. But you can configure sucessful ASBR
summarization if summary adress (170.10/16 for example) include network
in external (RIP, IGRP..) routing domains.
If you want explicit control of mutual redistributions just use
route-maps or distribute-lists.
