I had looked at your Plan,
Plan is OK, but one main thing I noticed is that the Space (distance) from Building North side to Boundry wall, is Less than the Space (distance) from Building South side to Boundry wall.
Always North side to Boundry wall from Building wall distance to be more than that of the South (even by 6 inch more), unlike in yours. So if ossible make that alteration. Leave more space at North.
1) Direction means it applies to PLOT, Building and also individual rooms. Not limited to Building only.
2) It is not advisable that south side of Building more than that of North side.
3) Door Numbers doesn't really make much difference in Vastu, But odd number is good as per numerology.
4) Over head tank tank at South-west is OK. But Sump to be at Nort-east advisable either East side (or) North side , but not placing on the AXIS intersecting South-west and North-East.
5a) Use Teak wood Frame for Main door and Sol-wood frames for other doors, no problem.
5b) Use of Power for main power Transmission cables to Lay individual rooms 2.5 mm2 from Main circuit breaker, and for individual Lights , Fans , etc.. use 1.5 mm2 cables. (Use 4 mm2 Cables for Air-conditioners and Heaters.)
