In NSSA area LSA types allowed are type3,and 7. Wether the stybby areas allows type1 ,2 and 4 LSA's irrespective of total stubby r totally not so stubyy areas.
The wording of your question is difficult to read so I can only assume that what you are asking about is basically which LSA types are allowed in which OSPF area types. So here goes:
Regular area: LSA types 1-5
Stubby area: LSA types 1-3. While the OSPF specification does not explicitly prohibit sending an LSA-4 into a stubby area, it makes no sense, so for the practical case, assume that only LSA types 1-3 are allowed in a stubby area.
Totally stubby area: LSA types 1-3. However, the only LSA-3 that ever gets injected into a totally stubby area by an ABR is the LSA-3 containing a default route. More specific prefixes are never injected into a totally stubby area
NSSA area: LSA types 1-3 and 7. See the comment about LSA-4 in the description of the Stubby area, as it applies here as well.
NSSA Totally Stubby area: LSA types 1-3 and 7. See the description of the Totally Stubby area regarding the LSA-3 contents, as it applies here as well.
