Meiosis I: Prophase I, Metaphase I, Anaphase I, Telophase I
Meiosis II: Prophase II, Metaphase II, Anaphase II, Telophase II.

Prophase I: Leptotene, Zygotene, Pachytene, Diplotene, Diakinesis.

Chromosomes condense and attach to the nuclear envelope and synapses occur. Crossing over occurs in the Diplotene.
Chromosomes thicken and detach from the nuclear envelope.
Similar to mitosis, the centrioles migrate away from one another and both the nuclear envelope and nucleoli break down. (Diakinesis)

Metphase I: Microtubules attached to kinetochore.

Anaphase I: Chromosomes move to the opposite cell poles. Similar to mitosis, the microtubules and the kinetochore fibers interact to cause the movement.

Telophase I: The spindles continue to move the homologous chromosomes to the poles. Once movement is complete, each pole has a haploid number of chromosomes. In most cases, cytokinesis occurs at the same time as telophase I. At the end of telophase I and cytokinesis, two daughter cells are produced, each with the same number of chromosomes of the original parent cell.

Prophase II: Chromosome coil up, condenses and shorten, centrioles divided and move apart
Metaphase II: Centromeres align on metaphase plate
Anaphase II: Cntromeres split and daughter chromosome migrate to opposite poles
Telophase II: daughter chromosomes arrive at the poles’ cytokinesis commences

for meiosis 1...

prophase 1,metaphase 1, anaphase 1, telophase 1.
cytokinesis usually occurs simultaneously with telophase 1, resulting in two haploid daughter cell.
besides, there are no interphase between meiosis 1 and meiosis 2.
for meiosis 2...
prophase 2, metaphase 2, anaphase 2, telophase 2
