There are 6 general purpose Registers and Two special purpose registers:
General purpose registers(8 bit basically) are B,C,D,E,H,L and SPECIAL Purpose resisters are STACK PONITER,PROGRAM COUNTER these two are 16 bit registers.
If u want make general purpose registers as 16 bit registers, the combination is BC,DE,HL these are 16 bit pair registers
There are three temporary registers in 8085.one is used during calculation to keep data temporary and then move it to destination and others two are 'w' and 'z' which hold address temporarily...........all these three users can't use .It is only used by processor .....
1.General purpose register
2.Temporary register
a)Temporary data register b)W and Z registers
3.Special Purpose register
a)Accumulator b)Flag register c)Instruction register
4.Sixteen bit register
a)Program counter b)stack pointer
The register names in 8085 are... 8 bit registers: A - Accumulator
F - Flags
B, C, D, E, H, L - General registers
TEMP - Only used internally - not available for general use 16 bit registers: BC, DE - General registers
HL - General register with some special uses
SP - Stack pointer
PC - Program counter
In an 8085, the 8-bit registers are...
A, B, C, D, E, H, L
... and the 16-bit registers are...
AF (Accumulator/Flags), BC, DE, HL, IP (Instruction Pointer), SP (Stack Pointer)
The opcode and temp register are not listed because they are not part of the "programmer's view" of the architecture. They exist, but they are only "interesting", from a hardware perspective, and they can not be independently manipulated.
Register in 8085 are of two types: a) General purpose registers b) Special purpose registers
General Purpose Register,
Index Register,
Pointer Register,
Flag Register,
Segment Register.
The multipurpose registers in the 8085 are B, C, BC, D, E, DE, H, L, and HL.
A, f, b, c, d, e, h, l, sp, pc
8085 is a microprocessor designed by Intel
Microprocessor consists of different types of registers. They special purpose registers, general purpose registers, address registers, floating point registers and constant registers.
The '8085' in the 8085 microprocessor is the designation given to the microprocessor by Intel. The '5' means it is a single power supply (5 volt) version of the 8080, with enhancements.

8085 is a 8 bit microprocessor designed by Intel Co.
with neat diagram explain the system bus structure of 8085
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
different architecture.
In the 8085 microprocessor, the MOV instruction copies data between two registers, or between a register and memory. The MVI instruction differs only in that the source data is contained in the byte immediately following the opcode byte.
