As you have used the present tense form "spends", the underlined past tense forms are not natural. In all cases, you are talking about what generally happens.At 4 p.m. my neighbour rang up and SAID,' Is Dheeraj there with you?' Dheeraj, her son SPENDS most of his time in my garden playing with my children, so whenever she WAS not able to find him she RANG me up to ask me where he WAS.
Alternatively, change "spends" to "spent", and you will be consistently talking about regular past happenings.
