MIP :-
Mapped IP (MIP) is a direct one-to-one mapping of one IP address to another(public ip to private ip ) that means hiding some resources (server) from the public.

VIP :-
A virtual IP (VIP) address maps traffic received at one IP address to another address
based on the destination port number in the TCP or UDP segment header. For
example,
An HTTP packet destined for 1.1.1.3:80 (that is, IP address 1.1.1.3 and port 80)
might get mapped to a webserver at 10.1.1.10.
An FTP packet destined for 1.1.1.3:21 might get mapped to an FTP server at
10.1.1.20.
An SMTP packet destined for 1.1.1.3:25 might get mapped to a mail server at
10.1.1.30.
The destination IP addresses are the same. The destination port numbers determine the host to which the security device forwards traffic.

you can refer to Concepts and Examples Screen OS Reference Guide in Juniper web site

This is the definition. Maybe someone can post how they use it in their environment, since I'm currently not using DIP.

A dynamic IP (DIP) address pool is a range of IP addresses from which the device can dynamically take addresses to use when performing NAT on the source IP address of outgoing or incoming IP packets.

You can link three types of interfaces to Dynamic IP (DIP) pools: physical interfaces and sub-interfaces for network and VPN traffic, and tunnel interfaces for VPN tunnels only.
